WebAug 3, 2024 · A groyne or groin (in the United States) is a stiff hydraulic structure placed perpendicular to the beach from an ocean shore (in coastal engineering) or from a bank (in rivers) that stops water flow and prevents sediment transport. It is typically constructed of wood, concrete, or stone. WebA groin simply blocks a part of this normal transport of sand alongshore and causes it to accumulate in a fillet on the groin’s updrift side (the side from which the sediment is coming). The amount of sand transported past the groin is greatly reduced (or eliminated) to significantly impact the downdrift area.
